seems like I won't be able to make it work unless I cut my veins with paper

I will try other things and if one of them is successfull I'll post what made it work.

I figured that your default routing in N900 is pointing to WiFi. That means the N900 is connecting to Internet via WiFi instead of GPRS.

Since the script is made for routing traffic via gprs0, the PAN could not enable your client to access to Internet via N900.

Therefore, in this case the script must be modified from:

Code:

iptables -t nat -A POSTROUTING -o gprs0 -j MASQUERADE

To:

Code:

iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE

WorldKaoss, though you've already given up on further investigation, I hope someone else who wants to setup Bluetooth-PAN would be benefited from our conversations and discoveries.

It fixed those errors however it's still the same.

I took the liberty to ping the bluetooth IP of the phone while in PAN:

also, if I ping from the phone the IP of the pc's bluetooth it says:

and it remains that way.. no errors, no lost packets .. nothing.

I just woke up and I saw your message, if I don't fall asleep I'm going to reboot the device and try then, else I'll do this when I wake up for a long period of time (maybe in 3 hours)

Show me the ipconfig, route print, ifconfig and route just like you did before would help me in the investigation.

Also, you must run the script after pairing up and joining PAN. No reboot is necessary as far as I concern. The bluetooth chip in N900 is quite stable, the PAN could stop and restart multiple times fine without reboot.

it's still the same

let's say I pop in a Ubuntu CD (just using the Live CD)

what should I do there to setup bluetooth for tethering.
it may be a windows problem, so if it works in Ubuntu then I will have to reinstall the windows.

Could be Windows problem, but I really want to help you figure out the root of the problem before trying other platform. Like I said before, I suspected it's just networking issue.
